YARN-REEL FOR BEELING-MACHINES AND WIN DING-MACHINES.

Specification of Letters Patent. Patented Dec. 28, 1909.

Application filed March 17, 1909. Serial No. 483,951.

To all whom it may concern:

Be it known that I, JEAN 'Scnwnrrnn, a citizen of the Swiss Republic, and resident of .I-Iorgen, near Zurich, Switzerland, have invented certain new and useful Improvements in Yarn Reels for Reeling Machines and \Vinding-lllachines, of which the following is a specification.

Yarn-reels for reeling-machines and similar apparatus are usually made of wood. lint the reels thus far known have the drawback that, on the one hand, they are too bulky, so that the surface for the material is too small, and, on the other, they are so heavy that, when winding fine material, such as silk, there is too great a strain for the strength-of the same. A further drawback consists therein that the reels are too little elastic for windin the yarn on and off and consequently render the winding-up very ditlicnlt, and when the yarn which is being wound ofl' gets entangled, they are not sufliciently yielding, so that the thread frequently breaks.

'The present invention does away with these drawbacks. The same consists in the main in fastening to the front sides of the hub of the reel radially grooved clampingdisks by which the reel-flights are secured. The reel-flights are flattened on the side facing the hub of the reel, in order that thesame cannot be turned.

The accompanying drawin illustrates a sample form of construction of such a reel Figure 1' is a front view and Fig. 2 a side view, whereas -Figs. 3-5 are details on an enlarged scale.

Similar lettefs refer to similar parts throughout the several views.

a is the hub of the reel which is preferably made of wood and is rovided at both ends with pivots b. Upon t 1e front sides of the hub of the reel are screwed, as will be seen from Fi s. 3 and 5, clamping-disks f of metal provided with several grooves or channels 0.- Into these grooves are placed the metal reel-flights d. The'latter are provided at their upper end with several undulations, in order to. retain the cords e on which the yarn rests. .At the lower end they are flattened a little on the side facing the hub of the reel, so that the same cannot turn. In order to prevent the. single flights from falling out and to keep them in the right position, the wooden screws 9- or the like are firmly tightened. By this arrangement the Zurich, Switzerland this 2d day 0 surface on the reel on which the yarn rests is made much broader, because the flights extend beyond the hub, which was not the case with the reels thus far known. As, moreover, the reel-flights are formed of thin metal bars the whole ,reel becomes very elastic and the yarn can be easily placed on it and be wound ofl" without'any trouble, even if slightly entangled, without straining the yarn very much or breaking 1t. Reels of this kind are, consequently, especially suited forreelingsilk and fine cotton threads, but also for coarse materials they are of a decided advantage.

Another advantage consists therein that such reels are very light, that they can be easily taken to pieces and are by insertin other reel-flights, adapted to be transformed at once into reels for larger or smaller skeins.

A further advantage is that such yarnreelsare very cheap to manufacture.

What I claim as my invention and desire to secure by United States Letters Patent 1s l. A yarn-reel for reeling and winding machines comprising .a hub member having flat surfaces at the ends thereof,- plates overlying said end surfaces and 'provlded with a plurality of radially disposed grooves, said grooves forming with said end surfaces spoke sockets having each a Hat side, spokes within said sockets and having each a flat side complementary .to the fiat sides of said sockets and lying in intimate contact therewith, and means for holding said grooved plates to said hub ends.

- '2. A resilient yarn-reel for reeling and winding machines comprising a hub member having flat end surfaces, plates overlying said end surfaces and having radially disposed grooves formed therein providin spoke sockets, resilient wires within sai' sockets constitutin spokes, said wires hav- .connect the spokes in parallel pairs and provide means for winding the am on the reel,

and meansfor holding sai grooved plates to said hub ends; I The foregoing specification si JEAN SCHWEITER. In presence of WM. BAUMGARTNER J. SURBER.
